Similar to the Dutch Oven; the Canadian Oven needs at least 2 people to pull it off. One person farts on the sleeping victim's face then quickly grabs the covers the victim is using at the time. The other person tilts the victim's head so the farter can tuck the covers under the victim's head, making it difficult for the victim to escape.
